Java.lang.Byte.longValue() Method



The java.lang.Byte.longValue() returns the value of this Byte as a long.


Following is the declaration for java.lang.Byte.longValue() method

public long longValue()

Specified by

longValue in class Number


  • NA

Return Value

This method returns the numeric value represented by this object after conversion to type long.


  • NA


The following example shows the usage of lang.Byte.longValue() method.

package com.tutorialspoint;

import java.lang.*;

public class ByteDemo {

   public static void main(String[] args) {

      // create 2 Byte objects b1, b2
      Byte b1, b2;

      // create 2 long l1, l2
      long l1, l2;

      // assign values to b1, b2
      b1 = new Byte("127");
      b2 = new Byte("-128");

      // assign long values of b1, b2 to l1, l2
      l1 = b1.longValue();
      l2 = b2.longValue();

      String str1 = "long value of Byte " + b1 + " is " + l1;
      String str2 = "long value of Byte " + b2 + " is " + l2;

      // print l1, l2 values
      System.out.println( str1 );
      System.out.println( str2 );

Let us compile and run the above program, this will produce the following result:

long value of Byte 127 is 127
long value of Byte -128 is -128
